Abstract Here, we report a novel method for regulating the morphology of block copolymer assemblies through use reversible addition–fragmentation chain transfer dispersion polymerization in ethanol. In this method, poly( N , -dimethylacrylamide) is used as macromolecular agent, and side length ionic liquid monomer modified. A notable change alkyl-imidazole (1-alkyl-3-(4-vinylbenzyl) imidazolium tetrafluoroborate) was observed when modified from methyl to butyl. This phenomenon can be attributed structural alkyl imidazole monomers, which resulted enhanced solvent-phobic properties. The kinetics glass transition temperatures polymers were investigated. These results demonstrated that rate increased with increasing number chains, whereas temperature decreased. It provides approach synthesis utilization poly(ionic liquid) higher-order morphologies.
